Below, the structure of yarn clearer 15 is described in detail.
The yarn clearer 15 of present embodiment, will be used to detect foreign body contained in textile yarn 20 with the textile yarn 20
The determination part 51,52 of the uneven optical profile type of rugosity arranges up and down two-stage along the moving direction of textile yarn 20.First determination part
The color for being used for the light in the color of the light of measure and the second determination part 52 for determining in 51 is the relation of complementary color.
I.e., as described above, based on yarn clearer 15 foreign body detection sensitivity, because yarn clearer 15 is shone textile yarn 20
The color of the light penetrated and it is different.It is high for the detection sensitivity of the foreign body of the color of complementary color relationship with irradiation light, it is same with irradiation light
The detection sensitivity of the foreign body of the color of system is low.Therefore, foreign body is carried out by using the light source of the light for irradiating single color
Detection existing yarn clearer, in terms of the scope of the color of the foreign body that can be detected exist limit.
With regard to this point, in the yarn clearer 15 of present embodiment, the measure of the detection of foreign body will be carried out as described above
Portion arranges up and down two, and using the light of different colors in each determination part 51,52 detection of foreign body is carried out.And, two
The color of light used is set to the relation of complementary color in individual determination part 51,52.Thus, even with the light of one of color
The foreign body that cannot be detected, it is also possible to detected with the light of another color.As a result, no longer there is the different of the color that cannot be detected
Thing, can make to be improved tremendously based on the detection sensitivity of the foreign body of yarn clearer 15.
It is used for the color of the light of the detection of foreign body in determination part 51,52, as long as the relation of complementary color just can be using any
Color combination.In the yarn clearer 15 of present embodiment, being conceived to can be while realizes that polyacrylic detection spirit can be made
Sensitivity improves and can differentiate impurity the two effects, thus employs the combination of cyan and yellow.It is aftermentioned with regard to this point.
Additionally, the detection sensitivity of the rugosity with regard to the textile yarn 20 based on yarn clearer 15, the face of detection light used
Color is hardly impacted to it.The yarn clearer 15 of present embodiment, with the detection of foreign body the rugosity of yarn is simultaneously also carried out
Detection, therefore, the detection also to the rugosity of textile yarn 20 in the following description is illustrated.
First, yarn clearer head 49 is illustrated.Yarn clearer head 49 is constituted as resinous shell.In yarn clearer head 49
Inside, be configured with each composition (the first light source portion 61 described later, the first light accepting part 62, the second light that determination part 51,52 has
Source portion 63, second light accepting part 64 etc.).On yarn clearer head 49, formed for making weaving along the moving direction of the textile yarn 20
The yarn path 49a that yarn 20 passes through.Additionally, yarn path 49a is in the shape opened to the device face side of yarn clearer head 49
Shape.
Below, the first determination part 51 is illustrated.As shown in Fig. 2 the first determination part 51 is configured in compared with the second determination part 52
Yarn moving direction upstream side.Fig. 3 is, to cut off on yarn clearer head 49 perpendicular to the plane of yarn moving direction, and to illustrate clearing
The schematic sectional view of the structure of the first determination part 51 of the inside of device head 49.
First determination part 51 has the first light source portion 61 and the first light accepting part 62.As shown in figure 3, the first light source portion 61 has
Two light-emitting components 611,612, the first light accepting part 62 has two photo detectors 621,622.Described two light-emitting components 611,
612 are constituted as yellow led, and thus the textile yarn 20 to moving in yarn path 49a irradiates the light of yellow.Photo detector
621st, 622 constitute as photodiode, by the intensity transformation of the light of light is into electronic signal and sends to analyzer 55.This
Outward, the determination part of the type is referred to as by biaxial type determination part with the meaning with two light-emitting components.
Additionally, by resinous lamella lucida 36 between yarn path 49a and the first light source portion 61 and the first light accepting part 62
Separate.Via the lamella lucida 36 to the irradiation light of textile yarn 20, the first light accepting part 62 will via lamella lucida 36 in the first light source portion 61
Light light.So, by the way that yarn path 49a is separated with the first light source portion 61 and the first light accepting part 62, be prevented from because
Yarn bits that textile yarn 20 is moved and produced in yarn path 49a etc. are attached to the first light source portion 61 and the first light accepting part 62
On, therefore, it is possible to improve the maintainability of yarn clearer head 49.
First light-emitting component 611 and the second light-emitting component 612, with from different perspectives to moving in yarn path 49a
The mode of the irradiation light of textile yarn 20 is configured.First light-emitting component 611 and the second light-emitting component 612 with alternately either one light
Mode be controlled by analyzer 55.Thereby, it is possible to textile yarn 20 from two different directions irradiation lights.I.e., so
Biaxial type determination part can with multi-angle determine textile yarn 20, therefore, even if the section shape at the section of such as Fig. 3 is
Flat yarn, it is also possible to which the accuracy of detection for making foreign body and yarn rugosity is improved.
First photo detector 621 is configured in the opposition side of the second light-emitting component 612 across the mobile route of textile yarn 20.
Therefore, the first photo detector 621 can receive the transmitted light of the light being irradiated on textile yarn 20 from the second light-emitting component 612
Light.Another second photo detector 622 is configured in the contrary of the first light-emitting component 611 across the mobile route of textile yarn 20
Side.Therefore, the second photo detector 622 can will be irradiated to the transmitted light of the light on textile yarn 20 from the first light-emitting component 611
Light.
First photo detector 621 by the light from the first light-emitting component 611 will not direct irradiation configure in the way of thereon,
Also, by can by the reflected light light of the light being irradiated on textile yarn 20 from first light-emitting component 611 in the way of configure.
Second photo detector 622 by the light from the second light-emitting component 612 will not direct irradiation configure in the way of thereon, also, with
The mode of the reflected light light of the light being irradiated on textile yarn 20 from second light-emitting component 612 can be configured.
According to above structure, as shown in figure 3, when the first light-emitting component 611 lights, the first photo detector 621 will reflection
Light light, the second photo detector 622 is by transmitted light light.The diagram of situation when the second light-emitting component 612 lights is eliminated, should
In the case of, in contrast to the above, by transmitted light light, the second photo detector 622 is by reflected light light for the first photo detector 621.
Because above-mentioned transmitted light is that woven yarn 20 is blocked and by photo detector 621, the light of 622 light, therefore, if spinning
The rugosity of weaving the yarn line 20 changes, then the intensity of transmitted light also changes.Therefore, in analyzer 55, by photo detector 621,
The variation of the transmitted light of 622 light monitored, can detect that the rugosity of textile yarn 20 is uneven.
Because above-mentioned reflected light is that reflection occurs on the surface of textile yarn 20 and by photo detector 621,622 light
Light, therefore, with the color on the surface of textile yarn 20 correspondingly, the intensity of above-mentioned reflected light also changes.Therefore, in analyzer 55
In, detected by the variation of the reflected light to photo detector light, foreign body contained in textile yarn 20 can be detected.
Especially, in the first determination part 51 of present embodiment, using yellow led as light source, therefore, it is possible to sensitive
Degree detects well the foreign body of the cyan of the complementary color as yellow.On the other hand, it is difficult to detect yellow by the light source of yellow
Foreign body, but this point can be made up by the second determination part 52.
Additionally, textile yarn 20 is more thick, the area that 20 pairs of light of textile yarn are reflected is bigger, therefore reflected light is strong
Degree also becomes strong.Therefore, the intensity from the reflected light of textile yarn 20 also suffers from the impact of the rugosity of textile yarn 20.No
Cross, photo detector 621,622 is also by the reflected light of the part (such as the wall of yarn path 49a) beyond textile yarn 20
Light.The reflected light of the more thick part then beyond textile yarn 20 of textile yarn 20 is weaker, therefore, it is possible to will be from weaving
The variation of the reflected light of yarn 20 is offset.Thus, the intensity of reflected light is not affected by the variation of yarn rugosity, therefore, it is possible to height
Precision ground detection foreign body.Though additionally, omit diagram, in order to will suitably support from the variation of the reflected light of textile yarn 20
Disappear, and take following measures：The reflecting plate of suitable reflectance is set on the wall of yarn path 49a.
Below, the second determination part 52 is illustrated.Fig. 4 is to cut on yarn clearer head 49 perpendicular to the plane of yarn moving direction
It is disconnected, and represent the schematic sectional view of the structure of the second determination part 52 of the inside of yarn clearer head 49.
Second determination part 52 has the light accepting part 64 of secondary light source portion 63 and second.As shown in figure 4, secondary light source portion 63 has
3rd light-emitting component 631, the second light accepting part 64 have three photo detectors (the 3rd photo detector 641, the 4th photo detector 642,
5th photo detector 643).3rd light-emitting component is constituted as cyan LED, the thus weaving to moving in yarn path 49a
Yarn 20 irradiates the light of cyan.Photo detector 641,642,643 is constituted as photodiode, by the intensity transformation of the light of light
Into electronic signal and send to analyzer 55.Additionally, the determination part of the type is referred to as with the meaning with a light-emitting component
Single-shaft variant determination part.
Divided by resinous lamella lucida 36 between yarn path 49a and the light accepting part 64 of secondary light source portion 63 and second
Every.It is configured to：Via the lamella lucida 36 to the irradiation light of textile yarn 20, the second light accepting part 63 is via lamella lucida in secondary light source portion 63
36 by light light.
5th photo detector 643 is configured in the opposition side of the 3rd light-emitting component 631 across the mobile route of textile yarn 20.
Therefore, the 5th photo detector 643 can receive the transmitted light of the light being irradiated on textile yarn 20 from the 3rd light-emitting component 631
Light.3rd photo detector 641 and the 4th photo detector 642 with from the light of the 3rd light-emitting component 631 will not direct irradiation at it
On mode configure, also, so that the reflected light of the light being irradiated on textile yarn 20 from the 3rd light-emitting component 631 can be received
The mode of light is configured.3rd photo detector 641 and the 4th photo detector 642 are on device depth direction (above-below direction of Fig. 4)
It is arranged respectively at the both sides of the 3rd light-emitting component 631.
5th photo detector 643 relative to the vertical mode of optical axis configuring.Thus, it is double with as the first determination part 51
Spindle-type determination part is compared, and single-shaft variant determination part can incite somebody to action saturating on device depth direction (above-below direction of Fig. 4) with relative broad range
Penetrate light light.So, the determination part of single-shaft variant can be in relative broad range by transmitted light light, therefore, it is possible to extend detection model
Enclose, even extremely thick ribbon body also can be determined.
Analyzer 55 monitored by the variation of the transmitted light to the light of the 5th photo detector 643, can detect weaving
The rugosity of yarn 20 is uneven.Analyzer 55 is by the reflected light to the 3rd photo detector 641 and the light of the 4th photo detector 642
Reduction detected, can detect foreign body contained in textile yarn 20.
Especially, cyan LED is adopted as light source in the second determination part 52 of present embodiment, therefore, it is possible to sensitive
Degree detects well the foreign body of the yellow of the complementary color as cyan.On the other hand, it is difficult to detect cyan by the light source of cyan
Foreign body, but this point can be made up by the first determination part 51.Additionally, in second determination part 52, determining with first
Portion 51 similarly, take in order to the intensity of photo detector 641, the reflected light of 642 light will not be affected by yarn rugosity with
Lower measure：The reflecting plate of diagram is omitted in suitably configuration.
Below, the detection to the foreign body in analyzer 55 is illustrated.There is analyzer 55 following conduct first to detect
The function of portion 55a：The reflected light of the light of the first light accepting part 62 being had according to the first determination part 51 and the institute of the second determination part 52
The reflected light of the light of the second light accepting part 64 having is detecting the foreign body of textile yarn 20.
First test section 55a enters the measured value of the first light accepting part 62 and the reflected light of the light of the second light accepting part 64 with threshold value
Row compares, and judges the presence or absence of foreign body contained in textile yarn 20.For example, the situation of the textile yarn 20 for constituting in cotton fiber
Under, textile yarn 20 itself be white thus light reflectance it is larger, the reflectance of the light of coloured foreign body is relatively low.Therefore,
If coloured foreign body is contained in textile yarn 20, the reflected light from textile yarn 20 is reduced.Therefore, the first test section
In 55a, the little foreign bodies detection threshold of the measured value of reflected light than obtaining from the textile yarn 20 of foreign state has been preset
Value.When the measured value of the first light accepting part 62 or the reflected light of the second light accepting part 64 is below foreign bodies detection threshold value, the first detection
Portion 55a makes the judgement comprising foreign body in textile yarn 20.In the yarn clearer 15 of present embodiment, by the He of the first light accepting part 62
Second light accepting part 64 by for the reflected light light of the color of the relation of complementary color, therefore, by considering receiving for both sides as described above
The measured value in light portion, can detect the foreign body of all colours.Further, since the reflectance of light is different because of the color of light source, because
This, it is also possible to make the foreign bodies detection threshold value being compared with measurement result in the first light accepting part 62 and the second light accepting part 64
It is different.
Even if additionally, contain foreign body in textile yarn 20, also and the light accepting part 64 of non-limiting first light accepting part 62 or second
The light income of reflected light is reduced.For example, in the case where polyacrylic fiber is mixed in textile yarn 20 as foreign body, this poly- third
Alkene for white thus hardly reduce reflected light.Therefore, to detect that polypropylene is difficult by existing yarn clearer.I.e.
It is mixed into polypropylene also inconspicuous in the textile yarn 20 of white, if but dyeing textile yarn 20 in operation thereafter
Then only polypropylene is not colored and keeps white, accordingly, there exist the very noticeable problem of the white polypropylene.
With regard to this point, in the yarn clearer 15 of present embodiment, due to the light of the cyan used in the second determination part 52,
Therefore, it is possible to detect polypropylene.That is, polypropylene has the big characteristic of the luminance factor cotton fiber of the light to cyan.Therefore, if
Polypropylene is mixed in the textile yarn 20 of cotton fiber, then the reflected light of the light of cyan can increase.Therefore, the first test section 55a is pre-
First set the big polypropylene inspection of the measured value of the reflected light of the light of cyan than obtaining from the textile yarn 20 of foreign state
Survey threshold value.When the reflected light of the light of the second light accepting part 64 reaches more than polypropylene detection threshold value, the first test section 55a makes spinning
Judgement containing foreign body in weaving the yarn line 20.Thus, yarn clearer 15 can be removed polypropylene as foreign body.
But, as Japanese Unexamined Patent Publication 2007-212423 publications are disclosed, the impurity (bits) of stem and leaf of cotton etc. can be rear
Together be colored with cotton in continuous operation thus become inconspicuous, thus be do not remove can also benign foreign body.Phase
Instead, if by it is this do not remove can also benign foreign body remove, can be dropped based on the production efficiency of the package of spooling unit 10
It is low.Therefore, the first test section has the judegment part 55c for differentiating impurity.
If detecting foreign body, judegment part 55c judges that whether the foreign body is the foreign body of yellow.That is, such as Japanese Unexamined Patent Publication 2007-
As No. 212423 publications are disclosed, impurity be yellow to orange-yellow, therefore, it is determined that for yellow foreign body be impurity probability
It is higher.Specifically, foreign body is not detected by the measurement result of the first light part 62 of the reflected light light by sodium yellow, and
In the case of foreign body being detected in the measurement result of the second light part 64 of the reflected light light by the light of cyan, judegment part
55c makes the judgement of the color for yellow of the foreign body.
But, there is also in textile yarn 20 containing the probability of the yellow foreign body beyond impurity.Although yarn clearer 15 is not
The removal of impurity must be gone, but needs the yellow foreign body beyond the removal of impurity.Here, the yellow foreign body beyond impurity, is mostly at other
Operation in be mixed into the fibre plate (referred to as dyed yarn) of yellow in textile yarn 20.
Therefore, judegment part 55c is that impurity or dyed yarn differentiate to the yellow foreign body.Here, impurity is with " dark
And it is short " feature, dyed yarn has the feature of " color is light and grow ".Therefore, by the light to the irradiation cyan of textile yarn 20, impurity
" dark and short ", dyed yarn " color is light and grows " is thus able to be detected as foreign body.In view of case above, judegment part
55c is constituted as follows：Threshold value is arranged to the length of yellow foreign body, only in the situation for detecting the yellow foreign body longer than threshold value
Under, make the judgement that the yellow foreign body is dyed yarn.Aforesaid way can also be replaced or constituted as follows on its basis：
Threshold value is arranged to the concentration of the color of yellow foreign body, only in the case where the yellow foreign body lighter than threshold value is detected, the Huang is made
Color foreign body is the judgement of dyed yarn.
Additionally, when the light of yellow is irradiated to textile yarn 20, it is impossible to detect the foreign body of yellow, therefore, also cannot detect
The deep or light and length of the color of yellow foreign body.By irradiating Huang the yarn clearer 15 such as present embodiment, to textile yarn 20
The light of the color beyond color, can detect first the deep or light and length of the color of yellow foreign body.Therefore, only there are yellow light sources
Japanese Unexamined Patent Publication 2007-212423 publications structure in, it is impossible to carry out the differentiation of the dyed yarn of impurity and yellow.
As described above, the yarn clearer 15 of present embodiment, makes the light of yellow and the light of cyan carry out foreign bodies detection in combination,
Thus, impurity can be stayed and can removed the yellow foreign body beyond impurity.And, the yarn clearer 15 of present embodiment, by
The detection of foreign body is carried out in the light using cyan, therefore, polypropylene can be detected as described above.
Then, to analyzer 55 in the detection uneven to the rugosity of yarn illustrate.Analyzer 55 have it is following,
As the function of the second test section 55b：The transmitted light of the light of the second light accepting part 64 being had according to the second determination part 52, detection
The rugosity of the yarn of textile yarn 20 is uneven.
The measured value of the transmitted light of the second test section 55b monitoring light of the second light accepting part 64, when the variation of measured value exceeds
During permissible range, the abnormal judgement of the rugosity of textile yarn 20 is made.
Analyzer 55 also plays a role as speed obtaining section (translational speed obtaining section) 55d, the speed obtaining section 55d root
The translational speed of textile yarn 20 is obtained according to the transmitted light of the first light accepting part 62 and the light of the second light accepting part 64.That is, in this enforcement
In the yarn clearer 15 of mode, the first determination part 51 separates predetermined distance ground compared with the second determination part 52 on yarn moving direction
It is configured in upstream side.Therefore, the measure of the transmitted light of the measurement result of the transmitted light of the second light accepting part 64 and the first light accepting part 62
As a result compare and postpone in time.The delay of this time is proportional to the translational speed of textile yarn 20.
Speed obtaining section 55d to the measurement result of the transmitted light of the second light accepting part 64 relative to the first light accepting part 62 transmission
In time which kind of degree ground postpones to be detected the measurement result of light, and is obtained according to the testing result and above-mentioned predetermined distance
The translational speed of textile yarn 20.In the yarn clearer 15 of present embodiment, it is measured using the light source of the color of two species
Thus there is determination part 51,52 in the way of upper and lower two-stage, therefore, also this upper and lower two-layer configuration is directly used in into speed
Detection.The yarn translational speed for obtaining as described above is sent to unit control unit 50 etc., and for the volume of textile yarn 20
Around control.
As described above, the yarn clearer 15 of present embodiment have the first light source portion 61, secondary light source portion 63, the
One light accepting part 62, the second light accepting part 64, the first test section 55a, the second test section 55b.First light source portion 61 is to textile yarn 20
The light of irradiation yellow.The light with yellow for the cyan of complementary color relationship is irradiated in secondary light source portion 63 to textile yarn 20.First light
The light in the first light source portion 61 there occurs the reflected light light of reflection on textile yarn 20 in portion 62.Second light accepting part 64 is by second
The light in light source portion 63 there occurs the light transmission in the reflected light of reflection and secondary light source portion 63 textile yarn on textile yarn 20
20 transmitted light light.First test section 55a spins according to the detection of the reflected light of the first light accepting part 62 and the light of the second light accepting part 64
The foreign body of weaving the yarn line 20.Second test section 55b detects the rugosity of textile yarn 20 according to the transmitted light of the light of the second light accepting part 64.
By as described above using the relation that there is complementary color two colors light, even detection sensitivity is because of a side
Light source light and the foreign body of color that reduces, it is also possible to the foreign body is detected with the light of the light source of the opposing party.So, by
In can mutually be made up to invalid color with two light sources, therefore, the yarn clearer 15 of present embodiment can be with good spirit
Sensitivity detects the foreign body of all colours.Profit is carried out by the light source using the light source of any one party as the detection for yarn rugosity
With can seek the structure for simplifying yarn clearer 15 and seek cost to reduce.It is high to the reflectance of the light of cyan for polypropylene
Characteristic, yarn clearer 15 carries out foreign bodies detection using the light source of cyan as described above, thus, it is possible to detect polypropylene.Yarn clearer 15
Also foreign bodies detection is carried out using the light source that the complementary color of above-mentioned cyan is yellow, thereby, it is possible to detect the light by cyan well
Source is difficult to the cyan foreign body for detecting.
In the yarn clearer 15 of present embodiment, the first test section 55a has judegment part 55c, and judegment part 55c will reflect
The measured value of light is compared with threshold value, to being mixed in textile yarn 20 in impurity and the foreign body beyond impurity differentiate.It is miscellaneous
Matter is difficult to the color that detects in the light source of yellow, therefore, by the reflected light based on yellow light sources and based in addition
The reflected light of light be compared, yarn clearer 15 can differentiate whether the foreign body for detecting is impurity.
The yarn clearer 15 of present embodiment, with as the first light source portion 61 that accommodates, secondary light source portion 63, the first light accepting part
62nd, the yarn clearer head 49 of the resinous shell in secondary light source portion 64.The visible ray adopted in above-mentioned embodiment will not make tree
Fat is deteriorated, therefore, it is possible to the first light source portion 61 and secondary light source portion 63 are received in resinous shell.By by two light sources
Portion and two light accepting parts are housed in a shell, can compactly constitute yarn clearer 15.
In the yarn clearer 15 of present embodiment, the first light accepting part 62 not only by reflected light light, also by the first light source portion 61
Light transmission textile yarn 20 transmitted light light.On the moving direction of textile yarn 20, the first light source portion 61 and first receives
Light portion 62 configures spaced by a predetermined distance in the upstream side of the light accepting part 64 of secondary light source portion 63 and second.Yarn clearer 15 has speed
Obtaining section 55d, speed obtaining section 55d is according to the first light accepting part 62 and the transmitted light and above-mentioned regulation of the light of the second light accepting part 64
Distance obtains the translational speed of the textile yarn 20.If to the transmitted light from mobile textile yarn 20 in the textile yarn
The upstream side and downstream of 20 moving direction is measured, then the measured value in downstream exists compared with the measured value of upstream side
Temporal delay.Therefore, yarn clearer 15 can pass through the delay for detecting this time so as to calculate the movement of textile yarn 20
Speed.
In the yarn clearer 15 of present embodiment, the first light source portion 61 have two alternately luminous light-emitting components 611,
612.First light accepting part 62 has two photo detectors 621,622 of reflected light and transmitted light light.Secondary light source portion 63 has
There is a light-emitting component 631.Second light accepting part 64 has a photo detector 643 of transmitted light light.
First light source portion 61 and the first light accepting part 62 are constituted as the determination part of biaxial type.Secondary light source portion 63 and second receive
Light portion 64 is constituted as the determination part of single-shaft variant.The determination part of biaxial type can to textile yarn 20 from multiple directions irradiation light,
Therefore, even if the section shape of textile yarn 20 is flat to can also ensure that good detection sensitivity.The measure of single-shaft variant
The photo detector 643 vertical with optical axis is configured with portion, therefore, the detection range of transmitted light is wide.So, due to single-shaft variant and double
The determination part of spindle-type respectively has feature, therefore, combine the detection that can make yarn clearer 15 by making the determination part of both types
Can improve.
The automatic bobbin winder of present embodiment, with the winder 31 by textile yarn in package and measure movement
Textile yarn yarn clearer 15.Thus, automatic bobbin winder can form abnormal, the Gao Pin for eliminating foreign body and yarn rugosity
The package of matter.
Below, the variation of above-mentioned embodiment is illustrated.Wherein, in the explanation of following variation, for it is above-mentioned
The same or similar structure of embodiment, marks with above-mentioned embodiment identical labelling and omits the description.
In the variation, in the second determination part 52, as replacement cyan LED of secondary light source portion 63 ultraviolet LED is used.
That is, because polypropylene is higher to the reflectance of the visible ray of cyan to the luminance factor of ultraviolet light, therefore, by using ultraviolet
LED can be such that polyacrylic detection sensitivity further improves.
The close cyan of spectrum of ultraviolet, therefore, the complementary color of cyan is that the detection sensitivity of the foreign body of yellow is high, but cyan
Foreign body detection sensitivity it is low.Therefore, in the variation, in the same manner as above-mentioned embodiment, the first light source portion 61 is made
Use yellow led.Thus, equally in the yarn clearer of the variation, the foreign body of various color can be detected.
Further, since ultraviolet light deteriorates can resin, it is thus impossible to use resinous lamella lucida to yarn clearer head 49
36.Therefore in present embodiment, compound stone lamella lucida 36 made in Great Britain is used to yarn clearer head 49.Cheap resin can adopted
On this point of lamella lucida 36 of system, it is more highly preferred to merely with the above-mentioned embodiment of visible ray.
As described above, the yarn clearer 15 of present embodiment have the first light source portion 61, secondary light source portion 63, the
